APAR status
Closed as program error.
Error description
This was seen with a Java program using the Communications Server for Linux APIs. When the Java program encountered an error and attempted to produce a core dump, it encountered a hang in the /opt/ibm/sna/lib64/libsna_r.so library.
Local fix
Problem summary
USERS AFFECTED: All programs that use the multi-threaded SNA APIs. PROBLEM DESCRIPTION: Hang in SNA library after a fork(). PROBLEM SUMMARY: When a program using a multi-threaded SNA library calls fork(), this does not always get handled correctly.
Problem conclusion
The library has been corrected so the post_fork handler for the parent process does not reset the SNA resournces.
Temporary fix
/opt/ibm/sna/lib64/libsna_r.so
