On SL 7.1, 64 bit :
How often does/should BOINC 7.6.6 clean up the slot directories / remove empty slots ?
Empty slots should be reused somehow, shouldn't they ?

Situation :
0 - 3 are empty slot directories.
4 - 6 are used slot directories.
7 - 202 are empty slot directories.
After removing slots 7 - 202 , host has continued normally but did not reuse empty slot dirs 0 - 3, instead created new ones 7 - 10.

Is that how BOINCs slot usage strategy should work ?

Message 64881 - Posted: 13 Oct 2015, 22:33:39 UTC - in response to Message 64878.  

If possible update to a later BOINC version. 7.6.11 has a fix:
client: fix a bug introduced in commit [44c82be] which prevented the re-use of empty slots.
This bug affects only Mac / Linux / UNIX builds. It does not affect Windows.

Thanks Jord.

Will rebuild my Linux client from newer source to get rid of that bug.
