Hello,
We are having performance problems with one of our users. We are having a server (2.1.16) for about 8000 users. This server is a vmware vm with 8 cores and 32GB of RAM. Normally, it is working fine, but when one of our users access his email, then the load increases a lot and this high load is maintained while the user is connected.
Looking for problems with this user I have found that trying to move messages from one folder to another I have errors like:
doveadm(mctm@um.es): Error: zlib.read(/mail/users/mailboxes/um.es/mc/mctm/mdbox/storage/m.1486): corrupted data at 30152376 doveadm(mctm@um.es): Error: zlib_istream.seek(/mail/users/mailboxes/um.es/mc/mctm/mdbox/storage/m.1486) failed: Invalid argument doveadm(mctm@um.es): Error: zlib.read(/mail/users/mailboxes/um.es/mc/mctm/mdbox/storage/m.1473): corrupted data at 7175520 doveadm(mctm@um.es): Error: zlib_istream.seek(/mail/users/mailboxes/um.es/mc/mctm/mdbox/storage/m.1473) failed: Invalid argument
but a doveadm dump of these files shows no problem.
Is there any way to debug this problem? How could I fix it?-- Angel L. Mateo Martínez Sección de Telemática Área de Tecnologías de la Información y las Comunicaciones Aplicadas (ATICA) http://www.um.es/atica Tfo: 868887590 Fax: 868888337
