In case the execds are restarted, a different environment might be set (the raw one during boot, or the one of the root user [in case it got restarted by hand later on]). As these are inherited to the execd, they may behave different (limits, environment variables like $PATH/$LD_LIBRARY_PATH…). - -- Reuti -----BEGIN PGP SIGNATURE----- Comment: GPGTools - https://gpgtools.org iEYEARECAAYFAljVmogACgkQo/GbGkBRnRpAeQCgh26Ppnge/1RQw99OEmvs5kIh phQAoMOs/HtdldAwTeEM9MEn2DbNAItF =Z1jt -----END PGP SIGNATURE----- _______________________________________________ users mailing list users@gridengine.org https://gridengine.org/mailman/listinfo/users
