HFSS 11.2 crashing while starting up (Failed to start Core)

Hi,

since recently I am not able to run HFSS (v11.2 running on RHEL 3) anymore. While starting HFSS (either the GUI or the batch version) from the shell I get the following error message:

/prog/ansoft/hfss11/mainwin511/mw/bin/tools/core_services.common: line 9: 13505 Terminated watchdog "$MWWATCHDOG_TERMINATION_FILE"
Failed to start Core Services.
/prog/ansoft/hfss11/.setup_runtime: line 1290: 13445 Aborted regedit -c -e "${_output_file}" "${_reg_key}" >"${_reg_oelog}" 2>&1
/prog/ansoft/hfss11/mainwin511/mw/bin/tools/core_services.common: line 9: 13580 Terminated watchdog "$MWWATCHDOG_TERMINATION_FILE"
Failed to start Core Services.
/prog/ansoft/hfss11/.setup_runtime: line 1372: 13520 Aborted regedit -c "${_reg_file}" >"${_reg_oelog}" 2>&1
Error: Unable to set the delay before watchdog terminates to 15 seconds.

Click to expand...

The message just occurs without any crash before, and I have no old process running.

I don't have root access to the server (university department, admin doesn't know a solution) and just restarting the machine isn't an answer due to other simulations running.

Anybody knows this error and/or has a suitable solution? I would deeply appreciate that ...

Greetings,

ps: Searching for $MWWATCHDOG_TERMINATION_FILE on google I get one result:

I have no idea about the inner structure of HFSS or how the watchdog is interacting with it. But maybe one of you knows ...

Problem solved (brute force):

I deleted all HFSS configuration files in my home folder. I haven't identified the problem itself and needed to adjust HFSS settings again, but now work continues.
Maybe this helps somebody ...

greetings,
