cvs history: warning: history line invalid

[Martin d'Anjou]

Hello.

We've been getting these errors with cvs history:

cvs history: warning: history line 51999 invalid
cvs history: warning: history line 61598 invalid
cvs history: warning: history line 61602 invalid

Here is what's around line 51999 in the history file:

U3d061217|user1|~/projects/proj1/*0|proj1_a/design/core/flistsU3d061218|mdoyle|~/my_cvs_lib/*0|proj1_a/verif/rpa/vera|1.10|cri_bfm.vr
core/flists|1.6|flist_xgxs_most
U3d061217|user1|~/projects/proj1/*0|proj1_a/design/core/flists|1.5|io_list_core.txt

It seems two lines were concatenated together somehow, and the following 
line is missing the first part of the line.

Around line 61598, the whole line is missing:

61597 
U3d08c65a|user2|~/projects/my_cvs_lib/*0|proj1_a/design/core/rtl|1.41|core.v
  61598
  61599 
U3d08c65a|user3|~/projects/*0|proj1_a/verif/shared/vera|1.15|layer4protocols.vr 
 61600 
U3d08c65a|user3|~/projects/*0|proj1_a/verif/shared/vera|1.21|packet_src.vr

And 61602 the begining of the line is also missing...

  61601 
U3d08c65a|user3|~/projects/*0|proj1_a/verif/shared/vera|1.31|packetstack.vr
  61602 bist.v
  61603 
U3d08c65a|user3|~/projects/*0|proj1_a/verif/shared/vera|1.16|rxpacketstack.vr

I do not know how any of it happened.

How can I fix this problem?

Thanks,
