I am figuring this has to do with the user.sub file and still locked.
Any time subscription is access imap creates a new file user.sub.NEW
instead of user.sub and becomes a run-a-way process.
No matter what I do or know can change the subscription based files..
flat or skipless. Right now the file is a flat file and while
converting it to skiplist I get the same issue as above - imap process
or in this case cvt_cryusdb ll the processor resources and becomes a
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+
8621 root 25 0 86848 2284 1848 R 96.1 0.4 81:51.64
My log shows this:
Sep 16 20:25:27 mail cyrus/cvt_cyrusdb: skiplist: invalid magic
Also when I try to read the "converted" user1.sub file using less I lose
any ability with the terminal. I am so at a loss and have been really
digging around for days trying to figure this out..
We are using Ubuntu 8.04 on this particular amd 64 box running virtually
