@miconda there was a copy&paste error here in my description complete configuration looks like this: ``` # ----- db_cluster params ------ modparam("db_cluster", "connection", DB_URL_REDIS_READ) modparam("db_cluster", "connection", DB_URL_REDIS_WRITE) modparam("db_cluster", "cluster", "cluster1=>c1=9r0p;c2=0r9p") ``` So the configuration looks complete according to Readme. Still the debug prints i added revealed the len mismatch. I have workarounded it in db_cluster module by recalculating the len in db_cluster_init. Here is the patch including the change and debug prints: ``` diff --git a/src/modules/db_cluster/dbcl_api.c b/src/modules/db_cluster/dbcl_api.c index 111abcca2..b1ddcd9fc 100644 --- a/src/modules/db_cluster/dbcl_api.c +++ b/src/modules/db_cluster/dbcl_api.c @@ -264,27 +264,27 @@ db1_con_t* db_cluster_init(const str* _dburl) dbcl_cls_t *cls=NULL; str name;

But was thinking perhaps that the root cause is some changes in srdb1 lib.
