Just did the autoupgrade to 1.11 and now xolox starts fine that crashes. Uses 100% cpu and spawns threads all over the place. I am running win2kpro on a PIII 600 w/ 512 RAM w/ a cable modem at 250up/1000 down. I am sharing about 500 files in 5 directories. Earlier versions worked fine. Can't seem to keep 1.11 up and running. Any suggestions?

Both issues (locup with 100% SPU and thread usage) have been researched and reported, and will probably be fixed in 1.12.

Threads/Directories:
Five directories total, or 5 in the list, with a bunch of sub-directories? (Movies sorted by content, Audio sorted by artist and CD, etc.) Subtract 5 from the number of threads shown in taskman and compare that to the total number of (sub)directories you are sharing (remember to add 1 for the xolox/downloads dir) It should be the same. If not it's a new bug that I haven't seen before.

Lockups/CPU uage:
Does this happen every time you start up? Open a cmd box and type netstat, see if you are conencting to yourself on a loopback address. (127.x.x.x) If you are, and every time you connect, delete hostslist.txt and see if it stops. If not, it's a new bug that hasn't been seen. (at least not by me.)

I got the same problem, the 1.09 lockup after a hour or 2. 89 % Cpu use. byt after 1.11 update it lockup after 30 sek, high cpu util, and lots of treads. the best version was 1.0 some have it is getting worse.
My config is win2000 adv server. 850 Mhz Athlon, 640 Mb ram alot of disk. run like a dream, byt xolox !!(not so good).
Please its a great program really great. byt it is very buggy.
