Org.openhab.binding.gpio - Could not obtain lock

Hello friends.
I use BananaPi for openHab 2.4.
Installed system is Armbian with a kernel 4.18.18-sunxi.
I installed binding GPIO to control the relay in the amount of 26 pieces.
My binding version:
openhab> bundle: list | grep GPIO
234? Active? 80? openHAB GPIO Binding
235? Active? 80? openHAB GPIO IO Module
When I reboot the SBC into openHab, the errors are continuously displayed: 03-Jan-2019 12:10:30.378 [ERROR] [org.openhab.binding.gpio ] - FrameworkEvent ERROR - org.openhab.binding.gpio org.osgi.framework.ServiceException: Exception in org.apache.felix.scr.impl.manager.SingleComponentManager.getService() at org.eclipse.osgi.internal.serviceregistry.ServiceFactoryUse.factoryGetService( ~[?:?] at org.eclipse.osgi.internal.serviceregistry.ServiceFactoryUse.getService( ~[?:?] at org.eclipse.osgi.internal.serviceregistry.ServiceConsumer$2.getService( ~[?:?] at org.eclipse.osgi.internal.serviceregistry.ServiceRegistrationImpl.getService( ~[?:?] at org.eclipse.osgi.internal.serviceregistry.ServiceRegistry.getService( ~[?:?] at org.eclipse.osgi.internal.framework.BundleContextImpl.getService( ~[?:?] at org.apache.felix.eventadmin.impl.handler.EventHandlerProxy.obtain( ~[?:?] at org.apache.felix.eventadmin.impl.handler.EventHandlerProxy.sendEvent( ~[?:?] at org.apache.felix.eventadmin.impl.tasks.HandlerTask.runWithoutBlacklistTiming( ~[?:?] at org.apache.felix.eventadmin.impl.tasks.SyncDeliverTasks.execute( ~[?:?] at org.apache.felix.eventadmin.impl.tasks.AsyncDeliverTasks$ ~[?:?] at java.util.concurrent.Executors$ ~[?:?] at ~[?:?] at java.util.concurrent.ThreadPoolExecutor.runWorker( ~[?:?] at java.util.concurrent.ThreadPoolExecutor$ ~[?:?] at ~[?:?] Caused by: java.lang.IllegalStateException: Could not obtain lock at org.apache.felix.scr.impl.manager.AbstractComponentManager.obtainLock( ~[?:?] at org.apache.felix.scr.impl.manager.AbstractComponentManager.obtainStateLock( ~[?:?] at org.apache.felix.scr.impl.manager.SingleComponentManager.getService( ~[?:?] at org.eclipse.osgi.internal.serviceregistry.ServiceFactoryUse$ ~[?:?] at Method) ~[?:?] at org.eclipse.osgi.internal.serviceregistry.ServiceFactoryUse.factoryGetService( ~[?:?] ... 15 more

I ask for help. Tell me, please, in what direction to look for a solution to this error.

Did you follow ALL the pre-requisites for the GPIO binding in the docs?

Yes, I made all the necessary settings, except:
Manually set in openHAB configuration file, key gpio: sysfs
I did not understand what file to write it.
I also noted that if I stop openHab and run it again, this error may not appear.
Also, this error does not appear if I use a total of 8 gpio outputs arbitrarily.
