Mailbox server crashing!

[i2ambler]

I have two mailbox servers. store1 and store2. Whenever I connect to store1 for administration and make a change to the mta settings (this is all I checked so far) the store crashes - mysql stops, mailboxd stops, stats stop, etc.. They also disable... These services will not re-enable until I manually start them.

Has anyone seen this before?? This concerns me.
