I tried sending 10000 Tx out of my wallet and it made it freeze at block 91482, I went to check and repair my wallet and it comes up with a mismatch spent coins error:
23:04:32

checkwallet
23:04:32

{
"mismatched spent coins" : 1,
"amount in question" : 10000.00000000
}
23:04:58

repairwallet
23:04:58

{
"mismatched spent coins" : 1,
"amount affected by repair" : 10000.00000000
}
Not sure how to fix this issue, I have tried restarting the wallet, resyncing the wallet and everything else I can think of. Any ideas?
Does the repairwallet command not fix your issue? If not then I'll need to look into the function to see what could be going wrong. A workaround for this. If repairwallet is not working, is you could dump the private keys for your wallet to a text file, then re import them. Also could you tell me which client version and protocol version you are running?
Open Debug console window and type resendtx. Sometimes it will resolve it.
