I have a OpenVZ VPS running CentOS 5.7 that I've been using to get some sysadmin experience.

I found a log file called brcm-iscsi.log in /var/log and it's getting big (140 MB).

INFO  [Sun Dec 18 20:15:42 2011]Initialize logger using log file: /var/log/brcm-iscsi.log

And every second since then I've had that line. I don't quite understand what is going on, so I'm hoping someone could tell me how to fix the underlying problem rather than just deleting the log file. I did Google this and found http://drup.org/brcm-iscsilog-filling-hard-drive which seems to just disable iSCSI and ignore any more errors. Is there a better/safer/preferable way of stopping this error logging?

I don't know much about iSCSI - I get that it's a SAN protocol, but that's about it. I've certainly never setup any volumes outside of the disk space I got with my VPS. Could my VPS be relying on this in some way? I wouldn't want to trash it, although I'm getting quite practiced at reloading the VPS... I also wouldn't want to screw up anyone else's nodes.

Thanks in advance for helping the n00b.

Google it and you come up with plenty links (Check out this one, for instance https://groups.google.com/forum/#!topic/open-iscsi/S3ps_mqzd_k) If you do not know what iscsi is (basically, SCSI over the wire: low level access to network disks) chances are good you won't be using it any time soon so you can remove/stop all the related cruft.
