I have been doing an imported restore of 5 servers for 5 months without a
problem.
Recently I had a file system fail and my backup up scripts were not up to
date, and
I have had to modify them.
Since then only 1 of the 5 restores has fails with the following error

2003-09-10 16:22:53 525941 525939 The ON-Bar process 526085 exited with a
problem (exit code 255 (0xff), signal -1).
2003-09-10 16:24:03 526080 525941 ERROR: Unable to open connection to
server:
could not fork server connection.

Previous threads on similar errors have suggested file permissions.

I have checked all the files I can think of and they are all on long
standing
file systems. There is disk space on all file systems.

I have run oninit -i using the same onconfig with only physdbs and number of
logs changed,
and that worked fine.

The Online log is not being written to.
With bar_debug set to 5 there is no output.
If bar_debug is set to 7 there is 17MB in 27 minutes before an error shows
in bar_act.log.

Any suggestions of what else to check ?

Well, you could check the storage manager logs but I'm guessing from
the behavior of onbar that they do not show anything. Sometimes these
could be a kernel issue, so make sure that your kernel settings are
what is recommended in the
"$INFORMIXDIR/release/en_us/0333/IDS_<version>" file. You could also
try setting BAR_DEBUG to 9 and seeing of there is any thing extra.

You didn't mention what operating system you are running on, but most
have a utility to record the messages between a process and the
operating system. For instance, on Solaris the utility is truss, and
it works similar to:

truss onbar -b -w -L 0 > truss.out

Have your OS vendor read the truss output. I know of someone who had
similar behavior to what you are seeing and trussed their onbar
process. They received an onbar return code 159 which is "BAR_BUG",
and has a case open with Informix support. The onbar return codes are
in the back of the Backup and Restore Guide (chapter 11?).

Good luck. Hope this information helps.
