Description Alan Conway 2008-12-19 19:55:49 UTC
Description of problem:

Running a client that mcasts faster than it dispatches, aisexec logs this messages:

Dec 19 17:39:13.126592 [MAIN ] Library queue is full, disconnecting library connection.

and becomes unresponsive, clients attempting to connect hang indefinitely.

How reproducible:

Easy.

Steps to Reproduce:

Run attached client, a modified cpgbench.c that multicasts in one thread and dispatches in another. An even simpler way to reproduce the problem is to take the original cpgbench.c and just comment out the cpg_dispatch line.
