<div dir="ltr">Hi there,<div><br></div><div>We've been fighting the same error for the last couple of days, and it turned out that the root cause is a data error (actually a character encoding issue in the labels) - basically this means that the lock issue in its own is not really helpful.</div><div><br></div><div>You've mentioned that the data is coming from an NFS share - maybe worth checking the I/O rates?</div><div><br></div><div>Cheers,</div><div>Attila</div></div><br><div class="gmail_quote"><div dir="ltr">Pestereva, Anna <<a href="mailto:apestereva@aerialservicesinc.com">apestereva@aerialservicesinc.com</a>> ezt írta (időpont: 2016. júl. 26., K, 0:45):<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Well, so far the most sure fix has been to explicitly configure caches with <i>disable_storage: true</i>. Although it is a relief to not see errors without changing functionally for most layers (since cache is not stored anyway for mixed format sources) - the original question remains open, why would those errors appear in the first place? We'd prefer to store tiles for caches/sources that support it.<br><br></div>Also, would it be correct to say that it is the best practice to explicitly disable storage for caches that don't save tiles anyway?<br></div><div class="gmail_extra"></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Jul 22, 2016 at 5:25 PM, Pestereva, Anna <span dir="ltr"><<a href="mailto:apestereva@aerialservicesinc.com" target="_blank">apestereva@aerialservicesinc.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div><div><div><div>A little more information if it can help anyone notice the reason/solution:<br><br></div>- errors occur with caches based not on just mixed sources, but also with caches based on single wms source, where cache tiles are being physically saved to disk.<br></div>- errors occur only with the most frequently used caches<br></div>- configuring and using a new cache with all the same settings, but a new name, helps temporarily.
