Hi
I've just encountered a similar performance issue which I have never
noticed on earlier Roundcube versions up to 0.2.1. One single PHP
process was hanging for a looooong time (don't remember, but must have
been 5min+, might as well have been hanging for hours). I was killing
this process and it was gone, no other processes hanging.
here's my current setup (https://webmail.onlime.ch/):
- Roundcube 0.2.2
- Debian Lenny 5.0.1
- Apache 2.2.9
- PHP 5.2.9 (patched with Suhosin 0.9.7 + module 0.9.27 enabled)
- PHP running as CGI under Apache's SuExec
Before killing the process I checked /proc/<PID>/environ to figure out
it was Roundcube. If any Roundcube developer is interested in my
environment variables, I can send you the whole output of /proc/<PID>/
environ off-list. I don't like to post it here for privacy/security
reasons.
Just some information that might help:
HTTP_REFERER=https://webmail.onlime.ch/?_task=mail&_action=preview&_uid=4786&...
REQUEST_URI=/?_task=mail&_action=get&_uid=4786&_mbox=INBOX&_part=49
HTTP_USER_AGENT=Mozilla/5.0 (Macintosh; U; PPC Mac OS X; de-de)
AppleWebKit/523.12.2 (KHTML, like Gecko) Version/3.0.4 Safari/523.12.2
We are talking about a very low volume Roundcube installation, usually
just 5-10 mails sent per day. It's running on a 2x Xeon Quad Core
E5405 2,00GHz / 8GB RAM machine, a powerful server that has a load
average of 0.2
So far, that's the first time I noticed such weird behavior with
Roundcube. I hope it's nothing serious. Good luck in bughunting! thx
Take care Philip

Hello,
I've recently installed Roundcube 0.2.2 for our users on 1024 RAM with 3Mhz cpu server. But the problem was appearing with high server load. According to the logs we have about 700 messages sent everyday and
about 3500 successfull and not sucessfull logins. In the period of all day load is increasing and after midnight it can be about 9 and it
caused by Apache processes. That is very strange because in that period almost
all users are sleep and we have only few logins and sent messages. This is only one virtual host running on the host. I've tried to use Debian
Etch and Lenny.Aslso I can confirm that after apache restarting high load goes down
to 0.2-0.4 but then starts to increase slowly again. So as the temporary solution I use "apache restart" instead "apache reload" in logrotate
config.I guess the problem is in Roundcube somewhere? Dear RC developers. So can you comment this situation? Why it can
happen?Thanks. _______________________________________________ List info: http://lists.roundcube.net/users/
