Getting a %ASA-3-210007: LU allocate xlate failed from a 5540 firewall pair. I looked up 210007 in the Syslog Messages PDF and it says to check the memory. Memory is about a third utilized.
I do a
debug fover fail
on both the primary and secondary, and on the secondary I get:
Failed to rep un_xlate for outside 10.x.x.x1/56616 - inside x.x.x.249/2055 flg: 2001000 2000002
Failed to rep un_xlate for outside 10.x.x.x2/63588 - inside x.x.x.249/2055 flg: 2001000 2000002
There are two different 10-addresses, each with a different port (as shown) and repeating back and forth. The "inside" addresses are always identical. These debug messages go on and on and on and there's no sense that they'll stop.
sh xlate | inc x.x.x.249
and got a NAT address that didn't match either one of the debug un_xlate errors.
Both devices are on 8.4(5). I'm not showing any other errors. I'd try to compare the xlate tables, but they over 60 pages long.
Everything I see online says it's a bug, but was likely fixed with 8.4(2.3) (something like that). I don't necessarily want to just believe it and update if it isn't the case.
