Smartheap

There currently seems to be a memory leak on 2-tier batch servers when utilizing long-running procedures. Reaching an "out of memory" condition can cause the "Smartheap Memory Error" and a C++ Runtime error to show up.

Supposedly this will be fixed in SP5. Or, you can complain to your Microsoft reps and maybe they can backport the patch for you. ;)

AOC Files

As I'm sure many of you know, Axapta caches data on the local client in order to speed processing of requests. Well, many times in my job I've encountered situations where an AOC file has been determined to be the root cause of a serious issue. Many times that we have seen problem-PCs, they also have a large number of AOC files on the HDD. Naturally, we don't want to delete these, but it's always a good start on troubleshooting. And, just in case you didn't know, AOC files are stored under the Documents and Settings folder. Just do a search for *.aoc and make sure to include Hidden and System files. I've seen the size of these files jump up to 20 MB a piece...not a lot I know, but when you've got 100 of them on a PC...

Edit: Something I found just after I wrote this...Is Brandon George's little piece on it. It helps when you google "Axapta AOC".

Security Settings

For some reason, you can't access the UserGroupList, AccessRightsList, UserGroupInfo, SysSecurityFormTable, or SysSecurityFormControlTable tables from inside of Axapta. I query on these tables quite often from SQL, so this is quite strange...
