> Key: QPID-8512
> URL: https://issues.apache.org/jira/browse/QPID-8512
> Project: Qpid
> Issue Type: Bug
> Components: C++ Client
> Environment: QPID 0.8 on SuSE Linux Enterprise Server 15 (SLES), Service Pack 2 (SP2) (SLES 15 SP2)
> Reporter: Karthik
> Priority: Major

> QPID Threads in the client hang on shutdown. This issue seems to specifically occur in SLES 15 SP2 (SuSE Linux Service Pack 2). It was working fine on SLES 15 SP1 and older versions like SLES11, 12 etc.
> QPID Client/Broker Version: 0.8
> On debugging into the QPID code, observed that the hang occurs in this function and in the ::epoll_wait call.
> *Code-Reference*:

> {{ .}}{{..}}
