failed: out of memory

[Thomas Schulz]

We are running Bind on a Sun Sparc machine running Solairs 8. Bind is
built as a 32 bit executable as that is the default and is the way
libcrypto and libxml2 are built. We have been running Bind 9.9.5.
I am now trying Bind 9.9.6b1 as that claims to have fixed some memory
leaks.

For some time now Bind has stopped being able to do recursive queries
every couple of weeks and I have been just restarting it. I decided to
look into this and found it logging out of memory errors. This seems to
have started happening after I set up bind to sign our domain, adi.com.
The server is bluegill.adi.com. It is set up with 3 views. Two are internal
views and can do recursive queries. One is the external view and does
not allow recursive queries.

Since restarting named, this time Bind 9.9.6b1, I have been checking
the memory usage every day. The usage in pages of 8192 bytes for the
last 7 days are:
16,517  19,221  20,111  23,707  24,957  26,384  28,231  29,912

Note that this shows no signs of settling down. I am looking into
the possability of rebuilding Bind as a 64 bit executable as that
should take much longer to run out of memory.

A recient section of the log showing that the cleaner is running:
