Error description
During connection setup for ssl connections there appears to be some needed back and forth between the client and server. As currently written, during the accept, the socssllst thread can block forever while waiting for some response from the client, which, if for some reason doesn't come, prevents further ssl connections from being made for that listener thread's port. The stack trace and state of the socssllst thread would look like this: Threads: tid tcb rstcb prty status vp-class name 12 45bd7c58 0 2 cond wait sqcrypto 8cpu* socssllst yield_processor_mvp mt_wait sqcrypto_call_n ssl_accp accpsocket tlAccept slSQIind_accp pfConInd_accp ascInd_accp ASF_Call sql_listener startup
