Description Martin Tlustos 2012-11-08 08:14:33 UTC

after stopping nepomuk services and re-enabling them, kmail and virtuoso start to eat up memory (kmail both extra and within kontact). Virtuose takes twice the size I set it to (will file an extra bug report on that), kmail slowly keeps on rising in memory usage every time I switch folders, open a new email, write or the like. It starts around 23MB and rose to over 120MB, if embedded in kontact, it rose to over 220MB before I ended it.

Reproducible: Always

Steps to Reproduce:
1. start kmail
2. work
3. see memory usage rise
Actual Results:  
memory usage rises slowly

Expected Results:  
should stop after some time. Some growth is normal, but not that much.

It probably mainly is a problem with nepomuk (surprise, surprise!), as I started to see this behaviour after I stopped and re-enabled nepomuk services.

Around 100mb is OK for Kmail.
How much is virtuoso taking ?

mixedmaildir: don't use 1.5GB of memory when importing a very big folder

Subjobs pile up too fast because they are cheap to create and
because it's taking around 5 event loops for one to start.
