1. We have a problem in the interaction between
XFree86-4.4.0 <=> ssh (openssh-3.7.1p2 or 3.8p1) <=>
mathematica (5.0 or 4.2)
Assume I am logged into an X-session on "hosta" and then log into "hostb" via
ssh with X-forwarding. If I then start mathematica (the graphical frontend)
I get zillions of messages on stderr:
==================================================
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 38 (X_QueryPointer)
Resource id in failed request: 0x38
Serial number of failed request: 386
Current serial number in output stream: 386
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 38 (X_QueryPointer)
Resource id in failed request: 0x38
Serial number of failed request: 387
Current serial number in output stream: 387
......
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 38 (X_QueryPointer)
Resource id in failed request: 0x38
Serial number of failed request: 22790
Current serial number in output stream: 22790
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 38 (X_QueryPointer)
Resource id in failed request: 0x38
Serial number of failed request: 22801
Current serial number in output stream: 22801
==================================================
until I exit from mathematica. (If I don't do that fast enough the
mathematica window occasionally freezes.)
This did not happen with XFree86-4.3.0 and does not happen if I bypass the
X-forwarding via "DISPLAY=hosta:0", nor (as far as I know) with any program
other than mathematica.
2. Is this a known problem?
3. Please let me know if there is anything I can do to narrow down and/or
further diagnose this problem.
