Description
Error Message
n/a
Cause
Solaris 32-bit limit was hit
Resolution
In this instance, vxconfigd (the binary being debugged) was 32-bit:
# file /usr/sbin/vxconfigd
/usr/sbin/vxconfigd: ELF 32-bit MSB executable SPARC32PLUS Version 1, V8+ Required, dynamically linked, not stripped
The debug output file stopped growing at the 2 GB limit:
# cd /var/tmp
# ls -l
total 4198178
-rw------- 1 root root 2147483647 Aug 17 16:33 vx.out
The 2 GB issue is documented in an online article:

To work round the issue, a means of rotating such log files is needed. Solaris has a utility called 'logadm', which can be used for this purpose.
