Environment
Novell NetWare 6.5 Support Pack 5
Legato Networker 7.02.01
Situation
Abend: Deadlock detected waiting
for spinlock currently owned by CPU 00
Legato NLM's were calling intoWS2_32_gethostbyaddr or WS2_32_gethostbyname when this abend
occurred.
Memory allocation errors seen on
console once the new WS2_32.NLM was applied. Error allocating
-30351 bytes which was a negative number.
Resolution
Fixed in WS2_32.NLM dated Aug 3, 2006 or newer.
Workaround:
We were able to work around the memory allocation
errors by editing the HOSTS file and removing any characters
(I didn't' see any) but white space at the end of the HOSTS
file. Hit delete or backspace until you get to
the end of the last valid entry in the HOSTS file and then save
it.
Use command: "WS2_32 reload hosts" to reload new hosts data
into memory.
Legato was reading in garbage characters from the
SYS:\ETC\HOSTS file and passing in a bad length parameter to
WS2_32_gethostbyaddr(), thus causing the Winsock memory allocation
error.
