Fsys -H argument

Is there any documentation available giving details about the -H argument
for Fsys ?
I’m mainly interested on how to select the proper heap size.
I’ve got a 120 GB HD, I set the heap size to 20 GB and it’s working great so
far (I was receiving ‘too many open files’ during installation).
Now, since I don’t understand exactly what the problem was and I chose the
20 GB heap size randomly, I’m a little concerned about having that problem
again in 2 months at 3 AM in the morning when this system in production…
that’d be sad… :frowning:

Any comments would be greatly appreciated.
Thanks in advance!

Sigh. Search this newsgroup for the thread entitled “mounting MO
returns not enough memory”; the final posting there contains an
attachment which fully describes the situation, fixes and workarounds.

Thanks for your reply John, but I cannot find the thread that you mention
(my outlook has been giving me some trouble with newsgroups).

Could you please send me the attachment?

Thanks a lot!

We use something like -H 1000000 and it seems to work well. This gives Fsys
about 1MB of heap memory to work with.

It seems that about 1/4 of that is all we needed, so we decided to play it
safe and go for a million bytes. No problems so far.

Jeff.
