Assert error in vrt_selecthttp

[utdrmac]

Using latest 2.1.2 RPMs on RHEL 5.5

Using the default "default.vcl" and we get this error upon attempts:

varnishd[4528]: Child (4529) Panic message: Assert error in vrt_selecthttp(), cache_vrt.c line 118:

Tried to roll back to 2.1.1 but that just segfaults right away with no output similar to above. Going to rollback to 2.1 here in a bit and just keep rolling back until it works again.

rpm -qa | grep libevent libevent-devel-1.4.13-1 libevent-1.4.13-1

had to rollback to 2.0.6 and create our own RPMs

I can make no heads or tails of that backtrace under the assumption that you are indeed using a unchanged default.vcl.

I have no idea how you got handling=deliver in STP_recv, that sounds like buggy inline-C code ?
