Failed: error - Async indexing process not found

@uroni

I am having the exact same issue with several Win7 clients. Image backups work fine, but File backups all fail, with the urbackup service crashing. This was not a problem about a week ago, and started suddenly with multiple machines.

Clients are running version 2.1.6
Server is running version 2.1.19

Client OS: Windows 7 Home Premium x32
Server OS: Debian 9.1 x64

I have tried uninstalling client 2.1.6, rebooting, and installing the beta 2.2.2 client, (from this post: Async indexing process not found). Same issue - the service crashes every time when it runs file indexing. I have removed the beta 2.2.2 client, and went back to the 2.1.6 client and I can reproduce the issue by running File Backup.

I will try to send the crashdumps and the debug log file to bugreports@urbackup.org, but I worry about their size not going through email - crashdumps are 85MB. Please let me know an alternate method to upload the crashdump. I’m happy to upload them to Dropbox and share the link.

I would really like to help get this issue fixed. I’m a CrashPlan refuge, so I plan on replacing about 20 CrashPlan instances with UrBackup. So I have plenty of machines to test any fixes, and provide any logs or dumps needed, or test beta versions.

Thanks in advance.
