reaper-1 thread consuming 99.9% CPU #956

While using the jeromq library, we suddenly encountered an issue where the reaper-1 thread is consuming 99.9% CPU. The issue occurred unexpectedly, as it hadn't happened during previous runs. The stack trace of the reaper-1 thread is as follows:

"reaper-1" #35 daemon prio=5 os_prio=0 cpu=66154861.28ms elapsed=98947.99s tid=0x00007fe494583d10 nid=0x3d runnable  [0x00007fe4bd1ce000]
