Help solve the problem with errors world2.err

Question 1
My report errors (logservice) scored records with errors like --
glinkd-1: err: FATAL, Protocol Size Excceed (type = 80, size = 386)

gdeliveryd: warning: gdelivery:: dbcreaterole: failed. roleid = 1321328, retcode = 45
and
gamedbd: err: GetRoleBase, roleid = 631860, what = NOTFOUND

WTF?

Question 2
The server is working properly. Sometimes the world crashes with LINK, the world wrote in logs error "assert failed:" exp> = 0 & & sp> = 0 "in file player.cpp: 1924" WTF???
pls help correct the problem.

I think the mistake LINK happens from that which it accrues from the mobs or the spirit of true experience. At high values of the assessed experience, he goes into a negative value, which causes an error LINK. Maybe you have already met this problem?
