Hi Guys, I have a quite interesting problem.
I have two servers that replicate to each-other. Suddenly one of the accounts
is starting to eat a very large amount of disk space on, what basically is the
replica for this account. doveadm-server seems to hang and keeps on filling the
disk.
I came across this message in the logs:
Dec 8 07:36:40 <server> dovecot: dsync-server(<account>): Fatal:
pool_system_malloc(6291528): Out of memory
Dec 8 07:36:40 <server> dovecot: dsync-server(<account>): Fatal: master:
service(doveadm): child 883 returned error 83 (Out of memory (service doveadm {
vsz_limit=256 MB }, you may need to increase it) - set DEBUG_OUTOFMEM=1
environment to get core dump)
I’ve increased the vsz_limit to 5G so it has stopped complaining. Only… the
process never seems to finish. I’ve tried to export the mailbox using dsync:
dsync -Dv backup -u 'xxxxx' sdbox:/tmp/patrick_export/
However this process never finishes either. It looks like it stays in one of
the mailboxes and keeps on trying to copy messages.
Format of the mailbox is sdbox
Version of dovecot on all servers: 2.2.9
Any pointers for solving this problem?
Kind regards,
Patrick
