[Xorp-users] No more than 25 OSPFv3 neighbors fully adjacent?

[Che, Ting-Shuo T.]

Started XORP on Linux Embedded System and connect that to a test
equipment (emulating
OSPFv3 neighbors). Test equipment added neighbors one-by-one and all of
them enter "Full" 
state. After that, nothing in this setup is changed, for observation
purposes. 
 
When there are more than 25 neighbors, the following error messages
showed up through
xorpsh after waiting for more than 30 minutes.

After this error message, all neighbors becomes "Down" state as shown
at the test equipment
side. On the xorpsh side, no more OSPFv3 console command could be
accepted.

Similar problems also happens for more neighbors (30, 35, 40, etc.).
The only difference is
the number (such as 252, 257, instead of 258) following xorp_rtrmgr:
 
Any thought or tip on this is very much appreciated.
