Troubles with kmail indexes recently.

Greetings; kmail has taken to forgetting its index pointers quite often recently, so when I revisit a folder, I often find the displayed msg is the first one in the list sort, which in 2 folders which have no expiry set, I often find myself re-reading a msg thats 14 years old and nearly 100K msgs older than the current last msg. I have two spam related folders I expect kmail will have to frequently rebuild because some spam messages caught by spamd & procmail might be written directly to the full path of that directory, and the script that runs sa-learn -spam on the spam folder, moves those messages to the spam-hold directory so in case it wasn't spam I can rescue it and move it to the ham folder. Since the email corpus here is quite a few gigabytes, is this an indicator that kmail needs a larger memory allocation?, and if so, how do I give it another 100 or so megs? According to htop, its only using 1% of the 8GB in this machine. This is a 32 bit, pae enabled install of wheezy, all uptodate as of 30 minutes ago.
