This appears to be related to the big MOTD problem. I had used this same config with 1.5.2 before updating and had reduced the size of the MOTD to avoid garbage characters being displayed, crashes on /login etc. It seems that 1.6.0 is even more sensitive to MOTD size as it crashes on /login with the same MOTD text that worked with v 1.5.2

A quick tes showed that an MOTD of 1082 characters worked ok. MOTD with 1354 characters crashed on /login as described. v1.5.2 worked with MOTD of 2325 bytes.

further MOTD size testing on v1.6.0

1087 characters appeared to work ok.

1137 characters resulted in a couple lines of garbage code being displayed - the #c255# trick that worked for me with v 1.5.2 didn't help

1325 characters caused crash at login.

seems to be a buffer overflow or boundary exceeded in the 1087-1137 range, with severity increasing with additional size.

damn it... so my attempt at fixing it made it worse? GRR!

I think i'm going to have to try and tackle this problem from a different angle, because the "make sure it has some memory to store the MOTD in" method doesn't seem to be helping!

seems so.

I just updated to 1.6.0r2
I reloaded my 1.5.2 cfg with an MOTD of 2300 characters.
it loaded ok without any garbage code being displayed.
I then did login and after some delay, it caused a crash, but in a different way than before. This time in crtdll.dll instead of wcs.exe:

well, that could be a good or a bad thing...

good that it didn't crash in the same way, bad that it still crashed - lol

having similar problem as newb but i dont have a large motd yet i still crash upon attempting to login

you know km, changing #NEWLINE# to somthing a lil smaller such as \n or #line# could also help us reduce the amount o characters n the motd ...just a thought
