Victor, Is this true? Where did you hear that GEMPAK is no longer supported by UNIDATA? GEMPAK still appears on the UNIDATA web page and UNIDATA was still answering GEMPAK support questions as recently as 10/21/20: https://www.unidata.ucar.edu/support/help/MailArchives/gempak/msg06591.html It’s true that there has been no dedicated support person since the death of Michael James but Tom Yoskas has been fielding GEMPAK questions since. What you say is true of GARP gui, but not GEMPAK itself, as far as I am aware. Can anyone clarify? Thanks. Tom ______________ Tom McDermott Systems Administrator Earth Sciences Dept.

I switched all of my scripts to use the coarser resolution level3 data 😕👎 I will let you know if there is a fix for SAILS_1 in GEMPAK.

I have been troubleshooting offline with Daryl. So, from what I can tell, the level2 files for some radars (for whatever reason) are transmitting two volume scans per file. The radars in question appear random, but it might be related to a recent upgrade in ROC software or something. EDIT: the files that blow things up are SAILS_1!!! The file sizes are double because (surprise!) there are two timesteps due to this SAILS_1.

My questions: 1) Is your LDM queue holding an hour's worth of data `pqmon`? Do you know if your upstream sources are holding an hour's worth of data? Is your LDM logging anything exciting about switching upstreams etc ? 2) Do the file write timestamps on the files make sense? Such that the write time coincides with the end of the VCP transmission? 3) Do your file byte sizes match what is found on the files at AWS / my realtime site? https://mesonet-nexrad.agron.iastate.edu/level2/raw/KDVN/<https://nam05.safelinks.protection.outlook.com/?url=https%3A%2F%2Furldefense.proofpoint.com%2Fv2%2Furl%3Fu%3Dhttps-3A__mesonet-2Dnexrad.agron.iastate.edu_level2_raw_KDVN_%26d%3DDwMFAg%26c%3DCu5g146wZdoqVuKpTNsYHeFX_rg6kWhlkLF8Eft-wwo%26r%3DubRAum_abJ_VeyWwkZyVzQ%26m%3DYGiYowSlf11EYs4Iv7UoJRkpuOr3jxOGiNQ-V92hCYk%26s%3DkPnL1ECWMi6TOqj_F5_waUineWOSRDGN44ssfsddL5k%26e%3D&data=04%7C01%7Ctmcdermo%40brockport.edu%7C859625000ad94cdfee7108d8843ec095%7C696ec4990f244fd9b691252a2884ef3b%7C0%7C0%7C637404752357704581%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=1fmyljCz9wHjWbjIkF36aYiEp%2BMDw273N93UNJgAtTk%3D&reserved=0> Do you have a recent example (today / yesterday) of a 2x / 3x file?

As an example, compare your file sizes today for KDVN and KILX, both of which are in VCP 35. I'm using the standard hhmmssRadarII perl script to create the volumes off of LDM. Again, no issues for some sites, and then this memory error is popping up for others. I sense a change in file contents or format... Any/all ideas welcome.
