Netldi leaves defunct processes, eventually fails with too many open files

On Linux, it is possible to encounter a problem with exiting netldi child processes not being reaped properly, leaving defunct processes behind.  Eventually the netldi process runs out of file descriptors and fails with an error similar to:

Error: open(/opt/gemstone/locks/gemstone.hostid, O_EXCL | O_CREAT | O_APPEND | O_RDWR) failed with errno=24,EMFILE, The process has too many open files.

You can determine if you are subject to this bug by executing the following:

unix> ps -ef | grep defunct | grep gem


Periodically stop / restart the netldi process.

If this is insufficient, contact GemStone Technical Support.  It is possible to use the 3.2.14 netldi with older GemStone versions; download a 3.2.14 version of GemStone/64 and replace the $GEMSTONE/sys/netldid executable with the netldid from 3.2.14.  This should be carefully tested before using in production.  We have verified this work-around on and believe it should work on other 3.2.X versions.
