zimbra mailbox crashes on redolog

[jclevy]

Hi everyone,

Since I upgraded to ZCS 7.0.1, every few days Zimbra crashes.

I found in vim /opt/zimbra/log/mailbox.log.2011-04-12.gz :

2011-04-12 01:12:58,422 ERROR [MailboxPurge] [name=xxx@yyy.net;mid=21;] redolog - Redo logging to logger com.zimbra.cs.redolog.logger.FileLogWriter failed
java.io.IOException: No space left on device
at java.io.RandomAccessFile.writeBytes(Native Method)

However my disk does not seem full :

[root@mail log]# df -h
Filesystem Size Used Avail Use% Mounted on
simfs 16G 9.5G 6.6G 59% /
none 3.9G 4.0K 3.9G 1% /dev

If I issue a zmcontrol restart, Zimbra restarts with no problem.

Where can this redolog come from ?

Thanks in advance for your help
JC.
