Hi all,
I'm currently trying to see if I can speed up polling in a frontend I'm testing.

Something must be wrong on your side. If you take the example frontend under

this is correct, the fevme frontend is written to do 100% CPU-busy polling.

18 Feb 2008, Konstantin Olchanski, Bug Report, potential memory corruption in odb,c:extract_key()
|
It looks like ODB function extract_key() will overwrite the array pointed to by "key_name" if given an odb
path with very long names (as seems to happen when redirection explodes in the Safari web browser, via
db_get_value(TRUE) via mhttpd "start program" button). All callers of this function seem to provide 256

oOne additional comment. I was able to trace the setting of the error code DB_NO_MEMORY
to a call to the db_add_open_record() by mserver that is initiated during the start-up
of my frontend via an RPC call. I checked with a debug printout that I have indeed

Hi Tim,
I reproduced your problem and then managed to go through a procedure to increase the number of allowable open records. The following is the procedure |

16 May 2017, Konstantin Olchanski, Bug Report, problem with odb strings and db_get_record()
|
Suddenly the mhttpd odb inline editor is truncating the odb string entries to the actual length of the
stored string value, this causes db_get_record() explode with "structure mismatch" errors. (Not my
fault, You Honor! Honest!). For example, I see these errors from al_check() after changing
