We are experiencing a critical issue across all our Central monitored devices caused by persistent accumulation of temporary folders in C:\Windows\Temp.
Issue Details:
- Folders follow the naming pattern "waapi-" followed by 10 random digits (e.g., waapi-1234567890)
- Each folder contains a .sig file and hex-named authentication files
- Folders are created approximately every 15 minutes
- Folders are NOT being cleaned up automatically and persist indefinitely
- Accumulation rate: 500MB to 5GB per device per month
- Process Monitor traces confirm these are created by LogMeIn.exe processes
- Support suggested one-to-many or remote execution as possible culpript but we don't use any of those.
- Case #22000673 created.
Impact:
- all monitored devices affected
Timeline:
- Issue first observed around June/July 2025
- Currently affects: Any device with LogMeIn.exe installed.
- Software versions: devices are on agent version 16128
Temporary Mitigation: We have implemented PowerShell scheduled tasks to delete these folders as a workaround, but this addresses symptoms rather than root cause.
Request: Please confirm if this is a known bug and provide either:
- A permanent fix via software update
- Official guidance on preventing folder creation
- Internal cleanup utilities/scripts designed to address this issue
This issue is documented in your community forums but lacks official vendor acknowledgment or resolution.
