[ProgSoc] Crontab weirdness?
This one's been bugging me for some time now. We've been running our
daily/weekly backups via crontab. The OS is IRIX 5.3.
Occasionally, a seg fault(core dumped) occurs the moment crontab calls
the backup scripts. It's fine though when run manually. Apparently,
crontab runs everything using /bin/sh. Oringally, my scripts were
written in sh, and recently I rewrote them in csh. The seg faults were
happening way before this change though. The execution flow is
crontab -> admin (/bin/sh) -> backup (/bin/csh)
The 'admin' script calls 'backup' like this:
/pathname/backup > /pathname/backup.log 2>&1
and when I look at the resulting log, the first line is:
Segmentation fault (core dumped)
So it appears the seg fault occurs at the point where 'admin' calls
'backup', but I don't know why! Argh! All scripts are headed with
#!/bin/sh or #!/bin/csh as required.
If anyone could help out or provide some useful pointers then I'd
greatly appreciate it. TIA.
