Hi.
A week ago i migrated my Rails app to Rails 2.3.4 (from 2.2.2). And i
am using passenger 2.2.7 that spawns my app as a Rails app.
I faced one problem - my app hangs two or three times a day. I straced
hanged instances and founded, that they doing select call at some
descriptor. Then i discovered in lsof that descriptor is
RackRewindableInput. See what strace shows for this descriptor:
ruby 16632 deployuser 10u REG 8,1 35
1924608 (deleted) /tmp/RackRewindableInput20091207-16632-4uu3i-0
It never lies - /tmp/RackRewindableInput20091207-16632-4uu3i-0 dont
exists.
When application runs normally, there are no RackRewindableInput files
at /tmp.
Why application want to access this file and what can i do to avoid
this problem?
Thank you.
