Problem running 'lscm load'

'lscm load' does not work sometime while using rtc2git, a third party tool to migrate code and history from RTC to Git repository. https://github.com/rtcTo/rtc2git

I understand a question related to a third party tool may not be appropriate to be asked in this forum but looks like the issue is about scmtools itself rather than the tool.

What basically the tool does is described as below:

1. It initalizes an empty git repository and clones it
2. In this repository, it loads a newly created (which will be set to the oldest baseline possible) or existing rtc workspace
3. The baseline of each component of a given stream is determined
4. For each baseline a compare command will be executed
5. The result of the compare will be parsed to get to the necessary commit-information (such as author, comment, date)
6. The change will be accepted in the workspace
7. The corresponding git command will be executed to do the same change in the git-repository

Currently, I'm trying to migrate about 1000 histories and at times (about 1 in 100, frequency may different among attempts) 'lscm load' looks like failed and changes are not loaded into local repository.

However, when look at the eclipse client, it seems all desired histories are accepted in a workspace correctly and moreover, even those failed histories can be loaded individually without problem.

Does 'lscm load' have potential issue or is there any way to fix this?
