[Bug 135599] Re: [gutsy] kmail creates processes until out of memory

[Ivan Čukić]

The trigger is checking the accounts for new mail. The kio_pop3
processes start when kmail wants to get the messages - both when invoked
automatically (specified period of time) and manually, both using
regular pop3 and secured pop3. The problem is that the processes do not
stop. (it can be a bug in kdebase-kio-plugins, and not kmail, IMHO)

You can do
# watch -n 5 'ps x | grep -c kio_pop3'
and click the "get mail", "get mail" ...

p.s. the kio_pop3 processes do not stop when kmail exits. (not zombified
- but real running processes)

------

Just an advice for all that are affected by this problem (or trying to reproduce it), set the maximum process number per user first - this way your system will not hang:
Add the next two lines to /etc/security/limits.conf
*          soft    nproc  150
*          hard    nproc  200
(when you exit the kmail, you can killall kio_pop3 processes)
