[Samba] IE 5.01, Shell Folders, Windows 2000 and Samba 2.2.3a
Recently at my University we upgraded our Samba servers from 2.2.0 to 2.2.3a. After the upgrade, one of the server's(Solaris 2.6) loads increased dramatically. From an average load of 2 to sometimes as high as 20 during heavy use. This appeared to be almost exclusively from the Samba processes as a handful of those processes took up approx 5% of the CPU EACH. Doing a truss on these processes revealed that it was calling stat64 and chmod continuously on Windows shell folders for History and Cookies. These processes only appeared when the end user was using IE(further testing narrowed this down to only 5.01). Obviously our shell folders are pointed to a network mapped drive from the Samba server. After dealing with this for a day, we attempted to rollback to 2.2.0. This still didn't solve our problems and trussing the processes showed similar behavior(stat64 and chmod on the History and Cookies folder). After spending some time trying to find a solution to this problem, we discovered deleting the Cookies and History folders on each of the user's samba mounts resulted in fixing the problem. Has anyone else experienced this type of behavior, and if so were you able to fix it any other way? Are there any fixes for this type of thing? Thanks and hopefully I'm not being repetitive. Not sure what information is helpful, but here we go. Server - E450 running Solaris 2.6 with approx 150-200 clients at any time(during heavy loads). Running only as a file server(no DC). Workstations - primarily Windows 2000 with IE 5.01(there are others, but this is the majority of the clients). Again thanks for all the great work and any help you can possibly give with this problem. Douglas Pace Douglas.Pace@nau.edu 928-523-1655 Systems Programmer, NAU

Why are you storing histories and cookies to a network drive in the first place???? ########################## Darrel Clute, CCNA Partner/CEO Acumen Technology Group Clute Technologies PH-517-629-2571 ICQ # 153081120 ######################### ----- Original Message ----- From: "Douglas Pace" <Douglas.Pace@NAU.EDU> To: <samba@lists.samba.org> Sent: Monday, March 18, 2002 6:54 PM Subject: [Samba] IE 5.01, Shell Folders, Windows 2000 and Samba 2.2.3a> Recently at my University we upgraded our Samba servers from 2.2.0 to > 2.2.3a.
