Re: File compression causes crash
Trying to "compress" how?
How big is "too big"?
What does "will not be written" mean?

Not exactly the latest version, is it? Have
you installed any available patches?

Re: File compression causes crash
That shouldn't tkae the system down, but I guess it did.
THis probably has nothing to do with the compression and everything with the IO.
Try :
1) the advfs command below to find the file which had the IO error
2) Copying the input file to /dev/nul to make sure it can be read
3) Try a different output device for the compressed data
4) split the export file, or if this is Oracle, re-export with a maximum output size causing it to split.
5) check out your swxcr and its drives.
Good luck!
Hein.
AdvFS I/O error:

To obtain the name of the file on which
the error occurred, type the command:
/sbin/advfs/tag2name /data/.tags/23400

Resulting in a read error on /dev/re0c
The kernel crashes while trying to recover from the failed read. A supported version of the kernel might not crash, but it won't get your data back from the bad device. You need to fix that.
