Could not retrieve blame for file

[Tamas Csabina]

I got the following error in one of the repositories in Fisheye:

Wed Jan 16 12:33:13 GMT+100 2019: Repository index failed due to errorcom.cenqua.fisheye.rep.DbException: java.io.IOException: Could not retrieve blame for file src/userinterface/cfg_pages/pages/ui_cfgpage_work_water_func.c@5143e9bb085079c323b3949807c7cf2f8aa68430 java.io.IOException: Could not retrieve blame for file src/userinterface/cfg_pages/pages/ui_cfgpage_work_water_func.c@5143e9bb085079c323b3949807c7cf2f8aa68430 com.atlassian.fisheye.dvcs.handler.DvcsProcessException: Error while communicating with VCS: com.atlassian.utils.process.ProcessException: While executing: "E:\Program Files\TortoiseHg-4.5.3\hg.exe --config ui.verbose=false annotate -r 5143e9bb085079c323b3949807c7cf2f8aa68430 -c -f -l path:src/userinterface/cfg_pages/pages/ui_cfgpage_work_water_func.c" in [E:\ProgramData\Atlassian\fecru-home\var\cache\cc_ixspray\clone] com.atlassian.utils.process.ProcessException: java.lang.RuntimeException: Failed to match line pageWorkWaterFunc.remainingProgr = IxCleanGetRemainingTime(pageWorkWaterFunc.smcMode); using pattern: \s*([0-9a-fA-F]{12})\s*(.+?):\s*(\d+):.*? java.lang.RuntimeException: Failed to match line pageWorkWaterFunc.remainingProgr = IxCleanGetRemainingTime(pageWorkWaterFunc.smcMode); using pattern: \s*([0-9a-fA-F]{12})\s*(.+?):\s*(\d+):.*?

This with version 4.6.0 20180726094856.

If I force a re-run, the error is gone. But it comes back after a couple of days.

Any tips what is causing this, and how to fix this?

The cause of this error is likely that the repository cache in FishEye has become corrupt. 

The workaround for this case would be the following:

1. Stop FishEye/Crucible service;
2. Delete the repository cache from FishEye in <FISHEYE_INST>/cache/REPO_NAME;
3. Start FishEye/Crucible;

If you are still encountering the error, there is likely something environmental that is corrupting the file system or messing with the permissions of the cache.
