1 -Download the file attached to this article and gunzip it or decompress it with a compression tool.
2 - Look at the current size of /var/opt/quest/vas/:
du -sh /var/opt/quest/vas
3 - Modify vasd_init_linux, line 190, and if the size given is more than 35MB, set -o size=150m to 4 times the size. So if for example /var/opt6/quest/vas/ was 40MB, set -o size=160m. If it's smaller, keep the 150m.
4 - On the system, stop vasd.
5 - mv /etc/init.d/vasd /etc/init.d/vasd.orig
6 - cp ./vasd_init_linux /etc/init.d/vasd
7 - Start vasd.
