Re: Phoebus on Windows host causes IOC crash on WSL

Hi,

Thank you for your reply.

There is no specific reason for running inside WSL. Building the EPICS environment in Linux is simpler than in Windows.

It is OK for me to not use Phoebus, for I only use the OPI to observe PV changes. Camonitor is good enough, it is just not that convenient.

Best regards,

Zhibang

主题: Phoebus on Windows host causes IOC crash on WSL

Hi,

I would like to build the motorMotorSim module in my WSL, Ubuntu 24.04 LTS. And I have succeeded building the module, ran it and accessed the PVs from the host of Windows with caput,caget,camonitor...

But there is a wired thing that if I want to use Phoebus to access the PVs, the IOC will crash.

The Phoebus also runs on the Windows host.

motorMotorSim IOC on Ubuntu(WSL) --> successfully run

caget.exe/caput.exe on Windows(host) --> successfully access the PVs

Phoebus on Windows(host) --> cause the IOC crash

For example, if I run the motorall_x.bob in execution mode, the IOC will show such information:

epics> *** buffer overflow detected ***: terminated

Aborted (core dumped)

I have found there was a talk from 2010 saying that this could be an issue caused by the OS itself. I am not sure if WSL is related to this issue.

Could any one help with this? Thank you!
