 |

Hi all,
I found that there will be a memory leak if asterisk running day by
day without restart. Is it good to restart asterisk service daily?
What is the better way to restart it daily like apache?

What makes you think there is a memory leak?

Probably depends on the version of Asterisk, but I don't restart daily |

I don't know about a memory leak, but I've found too that Asterisk
benefits from a daily restart in all installations of any kind of
serious scale that I've managed. This tends to improve application
performance, mainly. Found this to be true of 1.2 and 1.4.
Of course, I could be completely wrong -- I have no real way of knowing
whether the solution corresponds genuinely underlying problem.

I have cron script that restarts daily by /etc/init.d/asterisk restart
- that way asterisk is completely stopped and then started again. Long
ago, for 1.2 this was helping to reduce crashes on working time.
Anyway - i prefer to restart if i have some inactivity time anyway,
rather than have a small chance that it will crash while lot's of
calls are going trough. So, if you have timeframe when you know for
sure that there won't be any calls, you can restart by initscript.
Otherwise, if you have low call volume in night-time, you may modify
safe_asterisk script to start asterisk anyway (even if it returns ok
exit stats that means shutdown), and then stop asterisk by "stop when
convenient")

Atis

Actually, I donno it is a memory leak or not. I have a server only
running asterisk. As time goes by, the free memory shown in the top
is decreased. After I restart the asterisk, the free memory comes
again. That's why I wonder if regular restart asterisk is necessary.
Use a crontab to restart asterisk is a way to do it but you have to
maintain a crontab. Is it possible to use logrotate instead? Or
other better way?

I observed the same behavior. Someone told me that that's a normal
feature of linux, it manages memory that way. If that's true, than it
isn't normal to see the same (large) amount of free memory over time
on a box running asterisk only. However, I rarely restart and it
hasn't caused problems. Here's mine right now:
09:14:39 up 73 days, 18:47, 2 users, load average: 0.00, 0.00, 0.00
67 processes: 65 sleeping, 2 running, 0 zombie, 0 stopped
CPU states: 0.1% user 3.9% system 0.0% nice 0.0% iowait 95.8% idle
Mem: 515460k av, 509416k used, 6044k free, 0k shrd, 80052k buff
152896k active, 191472k inactive
Swap: 477248k av, 0k used, 477248k free 242404k cached
'course, these days, half a meg isn't much  |

Gee, I only have 7 MB free! I must reboot to free some memory! And that
Asterisk is using so much memory!
In fact:
1. The system has some 100MB of free memory. almost all of it is used
for caching and such.
2. Asterisk overcommits memory: it generally asks the kernel huge
ammounts of memory, but doesn't really try to use them. At least with
Linux such overcommits are not claimed at all.

Do I detect a tiny bit of sarcasm here? Someone from Digium (or
elsewhere) might be able to jump in and explain the asterisk memory
strategy and why it doesn't have any detrimental effects on anything
else running on the same system. |

Sarcastic indeed. Indeed all those assertions were false.
Off-Topic:
The big memory consumer I have on my system is $GECKO_BROWSER. I
currently have iceape (seamonkey), after just one day of operation:
tzafrir 8186 1.1 53.1 763016 264008 ? Ssl Feb12 19:23 /usr/lib/iceape/iceape-bin
Iceweasel (firefox), epiphany and kazehakase don't seem to be much
different.
So I have no issues with the little copy of Asterisk on my desktop
system...

Guys, don't start panic here. This is perfectly normal memory status
for Linux. Linux automatically uses most free memory for disk cache,
leaving only few megabytes, and frees disk cache as soon as any
application requests. This has nothing to do with Asterisk.

Atis

So that?s why I?ve always get a red bar on home screen of the Trixbox?
Phisical memory is always at top most use, near 100% (green bar turns red on
high level of memory use), and below it there is Kernel / Application,
Buffers, Cached memory uses.
tks,

If you want to flush your disk cache to see how much memory is being eaten cache pages, try this:
echo 3 >/proc/sys/vm/drop_caches
