Hi there!

Everything was working fine on my zimbra box until today where I am receiving messages like this one when I am sending a new email:
msg - system failure: indexMessage caught IOException
com.zimbra.cs.service.ServiceException: system failure: indexMessage caught IOException
at com.zimbra.cs.service.ServiceException.FAILURE(Ser viceException.java:174)
at com.zimbra.cs.index.Indexer.indexMessage(Indexer.j ava:161)
at com.zimbra.cs.mailbox.Message.reindex(Message.java :421)

I had a look in the logs and zimbra is complaining that the directory /opt/zimbra/index/0/2/index/0/ already exists.

Can I safely erase this directory? It is not empty (far from it).

Any help anyone?
