The workaround is to add -DUSE_FLOCK_SERIALIZED_ACCEPT to the EXTRA_CFLAGS line in the Configuration file.
See src/conf.h to determine if your architecture is affected. This affects many architectures. >How-To-Repeat: >Fix: The permanent fix will likely involve using non-blocking listening sockets. But experimentation is needed to determine if it's faster to serialize accept()s than it is to deal with potentially many EAGAIN/EWOULDBLOCKs >Audit-Trail: >Unformatted:
