We've had a serious issue whereby the TS when it crashes re-spawns/cores continuously when its tries to re-start under load. I traced the issue to SNMP research library (a third party lib)- They use selects and what happens is the file descriptor number spikes under load after the crash as all the sockets get opened at once - this causes buffer overflow in the select (which their library is full of) as the fd allocated to the FD_SET is much bigger than the FD_SETSIZE of 1024 (which was a bitch to track down as the stack was corrupted and gdb therefore useless). Tracing why this happened on 3.2.0 and not 3.0.2, I find the sequence
of the plugin_init has changed - On 3.0.2 the sequence was in effect 1. plugin_init and then 2. init_HttpProxyServer. Whereas this has mysteriously been reversed on 3.2.0. In order to get our system to work in this crash case , I've patched ATS to flip them around like in 3.0.2.
i'll attach the patch we propose we need to use to get around this.
Is this actually a bug then waiting to happen in other systems - Or was there a reason to change this sequence?
