Hi Souri,

I checked the issue and I can confirm that something is happening with the copied data, and monetdb does not like it. This error occurs during the first copy into.

The error I get is
server5: /ufs/lsidir/monetdb/MonetDB/gdk/gdk_atoms.c:1306: strPut: Assertion `(v[i] & 0x80) == 0' failed.

while trying to load the data. And the trace reads

#4  0x00007ffff72d4c8f in strPut (h=0x7fffbc14d640, dst=0x7fffd4aa3c80, 
    v=0x7fffd4aa3dd0 "Leftover data '*data i am not sure i should share...(?)* "...) at /ufs/lsidir/monetdb/MonetDB/gdk/gdk_atoms.c:1306

So I suspect to be a parse error that is not treated as it is supposed to.

Can we use the main_schema, data, and queries you send me to open a bug report? or is it sensitive data? If we can use them, then I suggest you open a bug report for the correct person to see it and fix it.

Hello Team,

I had shared all the data with Lefteris. When database crashes we restore it
from the backup.

Thank you

Dear Souri,

as both Hannes and Lefteris already mentioned with their replies to your
earlier messages, we need detailed instructions (and data) how to reproduce
the problem, otherwise, we have no means to debug it.

We easily operate tables with thousands of columns and millions of rows in
MonetDB; hence, neither is expected to be a problem in general.

If your server crashes, and then fails to restart, this should be reflected
in the merovingian.log . Please re-consult the log and feel free to share
the relevant snippets.

If the server fails to restart and you fail to reconnect, how could you test
with inserting fewer records into the very same table or inserting all
records into a new empty table?

Best,
Stefan
