Can you tell me, what size of the WMS cache file do you have? It's usually in directory:

%LOCALAPPDATA%\Josm\cache\tiles

I'm interested in files:

WMS_BLOCK.key
WMS_BLOCK.data

[wiktorn]

In 10417/josm:

Fix block cache growing outside the limit.

• Missing setting of the block size prevented JCS to properly limit of the cache file size when using Block Disk. Set the block size to 4096
• Block Disk Cache do not reduce the size of the file, when setting the limit lower than the actual file size, so now JOSM will remove all the cache files by itself when limit is set to lower than before value
• Because of above two, bumped naming of the files to _v2 so older (possibly way above the file size limit) file will be removed

See: #12979, #12986

Hi,

here's the file listing:

17.06.2016 Ј. 10:38 426474166 TMS_BLOCK.data
17.06.2016 Ј. 21:26 3573998 TMS_BLOCK.key
15.06.2016 Ј. 23:16 2147483648 WMS_BLOCK.data
15.06.2016 Ј. 23:34 5754444 WMS_BLOCK.key
10.06.2016 Ј. 21:15 0 WMTS_BLOCK.data
14.06.2016 Ј. 23:23 4 WMTS_BLOCK.key

Thanks, this clarifies situation for me. As a workaround, you may either:

• work with JOSM latest
• remove the files by your self once such problems happens
• go to extended settings and set jcs.cache.use_block_cache to false. This is needed only till next release

[wiktorn]

BlockDisk is not supporting cache sizes larger than 2GB's, this is already reported in JCS:
​https://issues.apache.org/jira/browse/JCS-156

I've also provided them a patch with a fix for this. Hope that it will be included in JCS tree before we will release next JOSM.
