This is after a few days of running. It was ok after the start for decent period of time. Never seen this on 0.13.0.

@vayvanne can you provide some more details:

What version of bitcoin-core are you using?

List the version number/commit ID, and if it is an official binary, self compiled or a distribution package such as PPA.

Machine specs:
- OS:
- CPU:
- RAM:
- Disk size:
- Disk Type (HD/SDD):
Any extra information that might be useful in the debugging process.

This is normally the contents of a debug.log or config.log file. Raw text or a link to a pastebin type site are preferred.

Thanks!

Hi, That was windows 7 x64 laptop with 6 Gb RAM and HDD running bitcoin core v. 0.13.1. I have upgraded to 0.14.1 already. Now it works all right except I see: C:\>"%programfiles%\bitcoin\0.14.1\bin\bitcoin-cli" getmempoolinfo { "size": 164667, "bytes": 98544263, "usage": 299935536, "maxmempool": 300000000, "mempoolminfee": 0.00051578 } I use default maxmempool which is increased to 450MB in 0.14.1. But I still see 300MB.

I believe DEFAULT_MAX_MEMPOOL_SIZE is still 300 in v0.14.1. What makes you think it's changed to 450?

https://bitcoin.org/en/release/v0.14.1

The default -dbcache has also been changed in this release to 450MiB

The default dbcache size was increased to 450 MB. The default mempool size is still at 300 MB.

O, sorry, my bad... confused with borrowing from mempool for dbcache... Unfortunately can't rollback to 0.13.1 to reproduce initial issue again. Thank you.
