Threads Need Memory Too

Arun Sirpal notices a bug with fn_dump_dblog():

Using this command creates more threads and hidden schedulers (these will only go after a restart). Depending on what version of SQL Server you are on and what Service Pack you may or may not have this issue. It was fixed in SQL 2012 SP2 onwards. So be on the cautious side when running these sorts of commands.

Also I noticed Memory bloat for the sqlservr.exe. Nothing else was running on this server, just my fn_dump_dblog script.  Threads need memory too.

It’s good advice. ¬†Undocumented functions are probably more likely than documented functions to contain bugs.
