[Asterisk-Users] Avoided deadlock

[mattf]

Hello,

I had this problem a few months ago on a machine that I did a lot of
recording on. It was caused by slow disk access time. Asterisk would wait
for something to write to disk and basically freeze everything. It would
always eventually happen to the same machine no matter if I wiped it
completely and did a full reinstall. I fixed it by buying 4 new 320-SCSI
drives and a new 320SCSI RAID card, no problems since then(6 months).

I did report this to Digium several times, they were even in my machine a
few times to monitor it, they had no clue what was causing it, and the
ast_channel_walk_locked bug has no documentation anywhere about it(not much
help to look in the code either).

Hope this helps.
