Hello,
dovecot version 2.1, Freebsd.
At about 10000 process in the system it starts to beeing unresponsive all the operations takes forver with load getting >8.
- the CPU is 30% iddle, 25% free RAM,
- i do not connect this problem with NFS - no correlation between i/o and the slow down,
- indexes are on local SSDs
- no process limits has been hit - not in dovecot nor in the system itself
After a dovecot restart the problems are gone immediatelly - by the time the process number grow back to 10000 again which usually takes place quite fast in rush hours.
Any advice?
Thank you!
